nEsILIENr WHEEL.

To all whom it may 0 mm.- I I Be it known that'I, ALEXANDER IZEN, a

former subject of the Czar of Russia, who

has declared his intention of becoming a citizen of the United States, andwho is a' resident of the city ,of Detroit, Wayne county, Michigan, have invented certain new and useful'Improvements in Resilient WVheels, of which the following is a specification. i

My invention relates to improvements in.

forming a part of tliisspecification, and 1n which':

Figure 1, is a side elevation of a resilient wheel embodying the invention, portions thereof being broken away to expose underlying parts,

Fig. 2, a perspective View of one of the spring-seat parts employed in the construction 7 Figs. 3 and 4, enlarged sections taken on lines 33 and. 44, respectively of Fig. 1, and I Fig. 5, a perspective view of one of the toggle members employed in the construction.

The preferred form of construction, as illustrated in the drawings, comprises a wheel consisting of a hub 5 from which extend radial spokes 6. The outer ends of spokes 6 are rigidly connected by a rim member 7, upon the periphery of which is arranged an annular metallic channel member 8 secured thereto by screws 9.

Surrounding the member 8 is an annular rim member 10 of such diameter as to result in the formation of an annular space between said parts. The member 10 is formed with external and internal channels, as shown, a tire 11, preferably of solid rubber or other suitable material, being'mounted in the external channel and secured in position therein by cables or wires 11. Arranged in the annular space between the members 8 and 10 is a plurality of toggles 12, the respective ends of which are posi- Specification of LettersiPatent. Patented Oct. 14, 1919.

tioned in the channels at theadjacent sides ,of said members and pivotally. secured thereto by means of bolts l3 and cooperating nuts 13. In order to'protect the ends of said bolts, annular laterally projecting flanges 14 are formed upon the parts 8 and 10, as

.- clearly shown in Figs. 3 and 4, the outer edges of said flanges projecting beyond the ends of said bolts and thus serving as a means of protection for the same.

The toggles 12 are'arranged in pairs, and cooperating with each pair of toggles is a rectangular'frame 15 consisting of spaced parallel end members 16 which are connected at their ends by side members 17 there being preferably two members 17 at each side, the ends of which-are secured by electrical welding to the members 16." Each frame 15 is pivotally connected with the knee joints of the toggles cooperating therewith by bolts 18 and cooperating nuts 18,

"said bolts constituting the pintles of the knee joints, as will be readily understood.

The frames 15 are curved to conform with the curvature of the wheel rim, and the same are arranged concentrically with the rim parts, the employment of two toggles cooperating with each frame serving of course to hold the same in proper relative position between the adjacent sides of the rim parts.

Interposed between the adjacent ends of adjacent members 15 are helical springs 19, the ends of which securely embrace socket forming members 20 which project from the ends of each member 15. In the socket members 20 are arranged bumpers or cushion members 21 of rubber or other suitable cushioning material, the arrangement being such that in the event of breakage or disabling of the springs 19, said members 21 of the adjacent frames 15 will come in contact with each other and thus assume the burden of the disabled springs. The socket members 20 are positioned in alinement with the side bars 17 of each frame 15 so that any pressure exerted thereon will be borne by the bars 17 and not by the end members 16.

In order to effect lubrication of the pivotal joints between the toggle and the rim parts, and between the members or leaves of each toggle, each of the bolts 13 and 18 is formed with an axial oil passage 22, the inner end of which communicates with the bearing, the outer end thereof opening exteriorly and being provided with a removable screw plug 23 through which the oil may be injected, as will be readily understood.

lVith the construction set forth, 1t W111 be seen that in use, any Weight or load upon.

the Wheel will be transmitted to the'toggles l2 and the springs 19 cooperating there'- withfand thus said springs W111 serve to absorb any shocks or jars to which thq Wheel is subjected, filling the s am e function as the an, in a pneumat c tire. In case of-v excessive shocks or 1ars, or in case ofdisabling of the springs 19, the cushion members-21' Will, be brought. into, play. The arrange ment. is such. also that Where tllQJVhBBl 1s used for driv ng, considerable power W111 be saved through theaction of the springs and toggles.

In order to close the annular space be.-

tween the parts 8 and 10, so as to exclude dust and foreign matter therefrom, sheets 21: of suitable elastiematerial are fastened toitlie sides of members 8 and; lOspanning the sides of said annularspace, said me1n bers 2 1- b3111g secured in pos tion by bands held in positio'n by' nuts 13. (bile I have illustrated and describedthe preferred; form of, construction for carrying my invention into effect, this is capable.
